Heater Catalog - Watlow

Flexible HeatersPolyimide HeatersPolyimide is a thin, lightweight organic polymer film thatprovides excellent tensile strength, tear and solventresistance and dimensional stability. The polyimide heateris ideal for applications requiring low outgassing in avacuum or resistance to radiation, fungus and chemicals.Performance Capabilities• For operating environments as low as -319°F (-195°C),heater temperature as high as 392°F (200°C)• Watt densities up to 50 W/in 2 (7.75 W/cm 2 ) a• UR ® and C-UR ® recognitionsFeatures and BenefitsExcellent physical and electrical properties• Results in thermal stability over a wide temperaturerangeTransparent polyimide material• Allows inspection of internal detailsResistance of radiation and fungus• Can be used in a wide range of applicationsTypical Applications• Medical applications that require a clean, sterileenvironment• Laboratory research• Semiconductor processing equipment• Optical equipment• LCD displays• Computer equipment• Photographic equipment• Aerospace/defense, where low outgassing propertiesare requiredPTFE or PolyimideLeads Availablea Watt density limits are application dependent (operatingtemperatures, bonding method and heat sink).Polyimide withFEP AdhesiveSystem0.0065 to 0.008 in.
